[Schematica] Print on a server

I recently downloaded schematica to build on a skyblock server, the problem is that when I activate the printer, im getting kicked of the server because the mod is trying to place blocks behind me. So i wanted to know if it was possible to do something that will force the mod to place blocks only where I put my mouse or maybe just allowing me to place blocks over the build so that i can spam click without putting blocks everywhere.
